Learn how U.S. capital markets actually work — the foundation of the FINRA securities-licensing exams. Master the players (issuers, underwriters, broker-dealers vs investment advisers, and the regulators — SEC, FINRA, SIPC, the Federal Reserve), how securities are born (primary offerings, IPOs and the prospectus, private placements under Regulation D, shelf registration) and how they trade (secondary markets, exchanges vs over-the-counter, market makers, bid–ask spreads, settlement), plus the economic forces behind prices — monetary vs fiscal policy, interest rates, inflation, and the business cycle. Each question teaches the concept and names the classic mix-up (primary vs secondary market, broker vs dealer, monetary vs fiscal policy). Aligned to the FINRA SIE and Series 7/63/65/66 content outlines using original questions — never real exam items.
